Protection relay(继电保护) 外文翻译资料
Protection relayProtective relayingProtective relaying is that area of power system design concerned with minimizing service interruption and limiting damage to equipment when failures occur. The function of protective relaying is to cause the prompt removal of a defective element from a power system. The defective element may have a short circuit or it may be operating in an abnormal manner. Protective relaying systems are designed to detect such failures or abnormal conditions quickly and to open a minimum of circuit breakers to isolate the defective element. The effect of quick isolation is threefold: (1) it minimizes or prevents damage to the defective element, thus reducing the time and expense of repairs and permitting quicker restoration of the element to service; (2) it minimizes the seriousness and duration of the defective elements affecting on the normal operation of the power system; and (3) it maximizes the power that can be transferred on power systems. The second and third points are of particular significance because they indicate the important role protective relaying plays in assuring maximum service reliability and in system design. The power that can be transmitted across system without the loss of synchronism is the function of fault clearing times. It is apparent that fast fault clearing times permit a higher power transfer than longer clearing times. High-speed clearing of faults can often provide a means for achieving higher power transfers and thereby defer investment in additional transmission facilities.A protective relaying system is based on detecting fault conditions by continuously monitoring the power system variables such as current, voltage, power, frequency, and impedance. Measuring of currents and voltage is performed by instrument transformers of the potential type (PT) or current type (CT). Instrument transformers feed the measured variables to the relay system, which in turn, upon detecting a fault, commands circuit breaker (CB) to disconnect the faulted section of the system.An electric power system is divided into several protective zones for generators, transformers, buses, transmission and distribution circuit, and motors. The division is such that zones are given adequate protection while keeping service interruption to a minimum. It is to be noted that each zone is overlapped to avoid unprotect (blind) areas. The connections of current transformers achieve the overlapping. The general philosophy ofrelay application is to divide the power system into zones that can be adequately protected by suitable protective equipment and can be disconnected from the power system in a minimum amount of time and with the least effect on the remainder of the power system. The protective relaying provided for each zone is divided into two categories: (1) primary relaying and (2) backup relaying. Primary relaying is the first line of defense when failures occur, and is connected to trip only the faulted element from the system. If a failure occurs in any primary zone the protective relays will operate to trip all of the breakers within that zone. If a breaker is omitted between two adjacent elements, both elements will be disconnected for a failure in either one. This latter arrangement is illustrated by the unit generator-transformer connection in the power plant. On bulk power generating and transmission systems, primary protection is designed to operate at high speed for all faults. Slower protection may be used in less important system areas but, in general, any system area will benefit by the fastest possible primary relaying.If the fault is not cleared by the primary protection, backup relaying operates to clear the fault from the system. In general, backup relaying disconnects a greater portion of the system to isolate the fault. Backup protection is provided for possible failure in the primary relaying system and for possible circuit breaker failures. Any backup scheme must provide both relay backup as well as breaker backup. Ideally, the backup protection should be arranged so that anything that may cause the primary protection to fail will not also cause failure of the backup protection. Moreover, the backup protection must not operate until the primary protection has been given an opportunity to function. As a result, there is time delay associated with any backup operation. When a short circuit occurs, both the primary and the backup protection start to operate. If the primary protection clears the fault, the backup protection will reset without completing its function. If the fault is not cleared by the primary protection, the backup relaying will time out and trip the necessary breakers to clear the fault from the system.There are two forms of backup protection in common use on power systems. They are remote backup and local backup.(1)Remote backup. In remote backup relaying, faults are cleared from the system onestation away from where the failure has occurred.(2)Local backup. In local backup relaying, faults are cleared locally in the samestation where the failure has occurred. For faults on the protected line, both the primary and the backup relays will operate to prepare tripping the line breaker. Relay backup may be just as fast as the front line relays. When either of these relays operates to initiate tripping of the line breaker, it also energizes a timer to start the breaker backup function. If the breaker fails to clear the fault, the line relays will remain picked up, permitting the timer to time out and trip the necessary other breakers on the associated bus section.Computer relayingThe electric power industry has been one of the earliest users of the digital computer as a fundamental aid in the various design and analysis aspects of its activity. Computer-based systems have evolved to perform such complex tasks as generation control, economic dispatch (treated in chapter 11)and load-flow analysis for planning and operation , to name just a few application areas. research efforts directed at the prospect using digital computers to perform the tasks involved in power system protection date back to the mien-sixties and were motivated by the emergence of process-control computers a great deal of research is going on in this field, which is now referred to as computer relaying. Up to the early 1980s there had been no commercially availability protection systems offering digital computer-based relays.However, the availability of microprocessor technology has provided an impetus to computer relaying.*Microprocessors used as a replace*and solid state relays non provide a number of advantages while meeting the basic protection philosophy requirement of decentralization.There are many perceived benefits of a digital relaying system:1.Economics: with the steady decrease in cost of digital hardware, coupled with theincrease in cost of conventional relaying. It seems reasonable to assume that computer relaying is an attractive alternative. Software development cost can be expected to be evened out by utilizing economies of scale in producing microprocessors dedicated to basic relaying tasks.2.Reliability: a digital system is continuously active providing a high level of aself-diagnosis to detect accidental failures within the digital relaying system.3.Flexibility: revisions or modifications made necessary by changing operationalconditions can be accommodated by utilizing the programmability features of a digitalsystem. This would lead to reduced inventories of parts for repair and maintenance purposes4.System interaction: the availability of digital hardware that monitors continuously thesystem performance at remote substations can enhance the level of information available to the control center. Post fault analysis of transient data can be performed on the basis of system variables monitored by the digital relay and recorded by the peripherals.The main elements of a digital computer-based relay are indicated in Figure 9-59. The input signals to the relay are analog (continuous) and digital power system variables. The digital inputs are of the order of five to ten and include status changes (on-off) of contacts and changes in voltage levels in a circuit. The analog signals are the 60-Hz currents and voltages. The number of analog signals needed depends on the relay function but is in the range of 3 to 30 in all cases. The analog signals are scaled down (attenuated) to acceptable computer input levels ( 10 volts maximum) and then converted to digital (discrete) form through analog/digital converters (ADC). These functions are performed in the block labeled “Analog Input Subsystem.”The digital output of the relay is available through the computer’s parallel output port, five-to-ten digital outputs are sufficient for most applications.The analog signals are sampled at a rate between 210 Hz to about 2000 Hz. The sampled signals are entered into the scratch pad (RAM) and are stored in a secondary data file for historical recording. A digital filter removes noise effects from the sampled signals. The relay logic program determines the functional operation of the relay and uses the filtered sampled signals to arrive at a trip or no trip decision which is then communicated to the system.The heart of the relay logic program is a relaying algorithm that is designed to perform the intended relay function such as over currents detection, differential protection, or distance protection, etc. It is not our intention in this introductory text to purse this involved in a relaying algorithm, we discuss next one idea for peak current detection that is the function of a digital over current relay.Microcomputer-based RelayingA newer development in the field of power system protection is the use of computers(usually microcomputers) for relaying. Although computers provide the same protection as that supplied by conventional relays, there are some advantages to the use of computer-based relaying. The logic capability and application expansion possibilities for computer-based, relaying is much greater than for electromechanical devices. Computer-base relaying samples the values of the current, voltage, and by use of A/D converters, change these analog values to digital form and then send them to the computer. In the event of a fault, the computer can calculate the fault’s current values and characteristics, and settings can be changed merely by reprogramming. Computer-based relaying are also capable of locating faults, which has been one of the most popular features in their application. In addition, self-checking features can be built in and sequence of events information can be downloaded to remote computers for fast analysis of relaying operations.Computer-based relaying system consists of subsystems with well defined functions. Although a specific subsystem may be different in some of its details, these subsystems are most likely to be incorporated in its design in some form. The block diagram in Figure 13-1 shows the principal subsystems of a computer-base relaying. The processor is the center of its organization. It is responsible for the execution of relaying programs, maintenance of various timing functions, and communicating with its peripheral equipment. Several types of memories are shown in Figure13-1-each of them serves a specific need. The Random Access Memory (RAM) holds the input sample data as they are brought in and processed. The Read Only Memory (ROM) or Programmable Read Only Memory (PROM) is used to store the programs permanently. In some cases the programs may execute directly from the ROM if its read time is short enough. If this is not the case, the programs must be copied from the ROM into the RAM during an initialization stage, and then the real-time execution would take place from the RAM. The Erasable PROM (EPROM) is needed for storing certain parameters (such as the relaying settings) which may be changed from time to time, but once it is set it must remain fixed even if the power supply to the computer is interrupted.The relaying inputs are currents and voltages—or, to a lesser extent—digital signals indicating contact status. The analog signals must be converted to voltage signals suitable for conversion to digital from. The current and voltage signals obtained from current andvoltage transformer secondary windings must be restricted to a full scale value of +10 volts. The current inputs must be converted to voltages by resistive shunts. As the normal current transformer secondary currents may be as high as hundreds of amperes, shunts of resistance of a few milliohms are needed to produce the desired voltage for the Analog to Digital Converter (ADC). An alternative arrangement would be to use an auxiliary current transformer to reduce the current to a lower level. An auxiliary current transformer serves another function: that of providing electrical isolation between the main CT secondary and the computer input system.Since the digital computer can be programmed to perform several functions as long as it has the input and output signals needed for those functions. It is a simple matter to the relaying computer to do many other substation tasks, for example, measuring and monitoring flows and voltages in transformers and transmission lines, controlling the opening and closing of circuit breakers and switches, providing backup for other devices that have failed, are all functions that can be taken over by the relaying computer. With the program ability and communication capability, the computer-based relaying offers yet another possible advantage that is not easily realizable in a conventional system. This is the ability to change the relay characteristics (settings) as the system conditions warrant it. With reasonable prospects of having affordable computer-based relaying which can be dedicated to a single protection function, attention soon turned to the opportunities offered by computer-based relaying to integrate them into a substation, perhaps even a system-wide network. Integrated computer systems for substations which handle relaying, monitoring, and control tasks offer novel opportunities for improving overall system performance.International Journal of Electrical Power & Energy Systems继电保护1. 继电器当故障发生的时候继电器将电力系统的停电范围减小到最小，并且减小对设备的破坏。

Grounding System
• Formerly, many power systems were ungrounded systems using delta-delta transformers. Ungrounded systems suffer form several problems, including transient overvoltages that necessitate the use of two surge arresters for a single-phase transformer (one on each side of the winding), and trouble with rapid, automatic clearing of the very common phase to ground short circuit. • 以前，许多电力系统采用角型接线变压器，为不接地系统。 不接地系统会带来很多严重的问题，包括暂态过电压，因 此，即使是单相变压器，也需要分别在原边和副边绕组各 安装一个避雷器。而且对于非常常见的相接地故障的快速 自动切除非常困难。

• If the neutral is grounded, the bank tries to ground the feeder, and when ground faults occur on the primary side, the distribution banks will supply ground current. This usually causes a large number of blown fuses on wye-delta distribution transformers with grounded neutrals. • 如果中性点接地，….，当在原边侧发生接地故障 时，配电变压器组中有接地电流流过。这会导致 星型中性点接地接线的配电变压器的保险熔断。

Fundamentals of protection practiceThe purpose of an electrical power system is to generate and supply electrical energy to consumers. The system should be designed and managed to deliver this energy to the utilization points with both reliability and economy. As these two requirements are largely opposed, it is instructive to look at the reliability of a system and its cost and value to the consumer.One hand ,The diagram mast make sure the reliability in system design,. On the other hand, high reliability should not be pursued as an end in itself, regardless of cost, but should rather be balanced against economy,taking.Security of supply can be bettered by improving plant design, increasing the spare capacity margin and arranging alternative circuits to supply loads. Sub-division of the system into zones. each controlled by switchgear in association with protective gear. provides flexibility during normal operation and ensures a minimum of dislocation following a breakdown.The greatest threat to the security of a supply system is the short circuit,which imposes a sudden and sometimes violent change on system operation. The large current which then flows, accompanied by the localized release of a considerable quantity of energy, can cause fire at the fault location, and mechanical damage throughout the system, particularly to machine and transformer windings. Rapid isolation of the fault by the nearest switchgear will minimize the damage and disruption caused to the system.A power system represents a very large capital investment. To maximize the return on this outlay. the system must be loaded as much as possible. For this reason it is necessary not only to provide a supply of energy which is attractive to prospective users by operating the system ,but also to keep the system in full operation as far as possible continuously, so that it may give the best service to the consumer, and earn the most revenue for the supply authority. Absolute freedom from failure of the plant and system network cannot be guaran- teed. The risk of a fault occurring, however slight for each item, is multiplied by the number of such items which are closely associated in an extensive system, as any fault produces repercussions throughout the network. When the system is large, the chance of a fault occurring and the disturbance that a fault would bring are both so great that withoutequipment to remove faults the system will become, in practical terms, inoperable. The object of the system will be defeated if adequate provision for fault clearance is not made. Nor is the installation of switchgear alone sufficient; discriminative protective gear, designed according to the characteristics and requirements of the power system. must be provided to control the switchgear. A system is not properly designed and managed if it is not adequately protected.Protective gearThis is a collective term which covers all the equipment used for detecting,locating and initiating the removal of a fault from the power system. Relays are extensively used for major protective functions, but the term also covers direct-acting a.c.trips and fuses.In addition to relays the term includes all accessories such as current and voltage transformers, shunts, d.c.and a.c. wiring and any other devices relating to the protective relays.In general, the main switchgear, although fundamentally protective in its function, is excluded from the term protective gear, as are also common services, such as the station battery and any other equipment required to secure opera- tion of the circuit breaker. ReliablityThe performance of the protection applied to large power systems is frequently assessed numerically. For this purpose each system fault is classed as an incident and those which are cleared by the tripping of the correct circuit breakers and only those, are classed as 'correct'. The percentage of correct clearances can then be determined.This principle of assessment gives an accurate evaluation of the protection of the system as a whole, but it is severe in its judgement of relay performance, in that many relays are called into operation for each system fault, and all must behave correctly for a correct clearance to be recorded. On this basis, a performance of 94% is obtainable by standard techniques.Complete reliability is unlikely ever to be achieved by further improvements in construction. A very big step, however, can be taken by providing duplication of equipment or 'redundancy'. Two complete sets of equipment are provided, and arranged so that either by itself can carry out the required function. If the risk of an equipment failing is x/unit. the resultant risk, allowing for redundancy, is x2. Where x is small the resultant risk (x2) maybe negligible.It has long been the practice to apply duplicate protective systems to busbars, both being required to operate to complete a tripping operation, that is, a 'two-out-of-two' arrangement. In other cases, important circuits have been provided with duplicate main protection schemes, either being able to trip independently, that is, a 'one-out-of- two' arrangement. The former arrangement guards against unwanted operation, the latter against failure to operate.These two features can be obtained together by adopting a 'two-out-of-three' arrangement in which three basic systems are used and are interconnected so that the operation of any two will complete the tripping function. Such schemes have already been used to a limited extent and application of the principle will undoubtedly increase. Probability theory suggests that if a power network were protected throughout on this basis, a protection performance of 99.98% should be attainable. This performance figure requires that the separate protection systems be completely independent; any common factors, such as common current transformers or tripping batteries, will reduce the overall performance. SELECTIVITYProtection is arranged in zones, which should cover the power system completely, leaving no part unprotected. When a fault occurs the protection is required to select and trip only the neareat circuit breakers. This property of selective tripping is also called 'discrimination' and is achieved by two general methods:a Time graded systemsProtective systems in successive zones are arranged to operate in times which are graded through the sequence of equipments so that upon the occurrence of a fault, although a number of protective equipments respond, only those relevant to the faulty zone complete the tripping functiopn. The others make incomplete operations and then reset.b Unit systemsIt is possible to design protective systems which respond only to fault conditions lying within a clearly defined zone. This 'unit protection' or 'restricted protection' can be applied throughout a power system and, since it does not involve time grading, can be relatively fast in operation.Unit protection is usually achieved by means of a comparison of quantities at theboundaries of the zone. Certain protective systems derive their 'restricted' property from the configuration of the power system and may also be classed as unit protection. Whichever method is used, it must be kept in mind that selectivity is not merely a matter of relay design. It also depends on the correct co-ordination of current transformers and relays with a suitable choice of relay settings, taking into account the possible range of such variables as fault currents. maximum load current, system impedances and other related factors, where appropriate.STABILITYThis term, applied to protection as distinct from power networks, refers to the ability of the system to remain inert to all load conditions and faults external to the relevant zone. It is essentially a term which is applicable to unit systems; the term 'discrimination' is the equivalent expression applicable to non-unit systems.SPEEDThe function of automatic protection is to isolate faults from the power system in a very much shorter time than could be achieved manually, even with a great deal of personal supervision. The object is to safeguard continuity of supply by removing each disturbance before it leads to widespread loss of synchronism, which would necessitate the shutting down of plant.Loading the system produces phase displacements between the voltages at different points and therefore increases the probability that synchronism will be lost when the system is disturbed by a fault. The shorter the time a fault is allowed to remain in the system, the greater can be the loading of the system. Figure 1.5 shows typical relations between system loading and fault clearance times for various types of fault. It will be noted that phase faults have a more marked effect on the stability of the system than does a simple earth fault and therefore require faster clearance.SENSITIVITYSensitivity is a term frequently used when referring to the minimum operating current of a complete protective system. A protective system is said to be sensitive if the primary operating current is low.When the term is applied to an individual relay, it does not reter to a current or voltage setting but to the volt-ampere consumption at the minimum operating current.A given type of relay element can usually be wound for a wide range of setting currents; the coil will have an impedance which is inversely proportional to the square of the setting current value, so that the volt-ampere product at any setting is constant. This is the true measure of the input requirements of the relay, and so also of the sensitivity. Relay power factor has some significance in the matter of transient performance .For d.c. relays the VA input also represents power consumption, and the burden is therefore frequently quoted in watts.PRIMARY AND BACK-UP PROTECTIONThe reliability of a power system has been discussed in earlier sections. Many factors may cause protection failure and there is always some possibility of a circuit breaker failure. For this reason, it is usual to supplement primary protection with other systems to 'back-up' the operation of the main system and to minimize the possibility of failure to clear a fault from the system.Back-up protection may be obtained automatically as an inherent feature of the main protection scheme, or separately by means of additional equipment. Time graded schemes such as overcurrent or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back. In this way complete back- up cover is obtained; one more section is isolated than is desirable but this is inevitable in the event of the failure of circuit breaker. Where the system interconnection is more complex, the above operation will be repeated so that all parallel infeeds are tripped. If the power system is protected mainly by unit schemes, automatic back-up protection is not obtained, and it is then normal to supplement the main protection with time graded overcurrent protection, which will provide local back-up cover if the main protective relays have failed, and will trip further back in the event of circuit breaker failure.Such back-up protection is inherently slower than the main protection and, depending on the power system con- figuration, may be less discriminative. For the most important circuits the performance may not be good enouugh, even as a back-up protection, or, in some cases, not even possible, owing to the effect of multiple infeeds. In these casesduplicate high speed protective systems may be installed. These provide excellent mutual back-up cover against failure of the protective equipment, but either no remote back-up protection against circuit breaker failure or, at best, time delayed cover.Breaker fail protection can be obtained by checkina that fault current ceases within a brief time interval from the operation of the main protection. If this does not occur, all other connections to the busbar section are interrupted, the condition being necessarily treated as a busdar fault. This provides the required back-up protection with the minimum of time delay, and confines the tripping operation to the one station, as compared with the alternative of tripping the remote ends of all the relevant circults.The extent and type of back-up protection which is applied will naturally be related to the failure risks and relative economic importance of the system. For distribution systems where fault clearance times are not critical, time delayed remote back-up protection is adequate but for EHV systems, where system stability is at risk unless a fault is cleared quickly, local back-up, as described above, should be chosen.Ideal back-up protection would be completely indepen_ dent of the main protection. Current transformers, voltage transformers, auxiliary tripping relays, trip coils and d.c. supplies would be duplicated. This ideal is rarely attained in practice. The following compromises are typical:a. Separate current transformers (cores and secondary windings only) are used for each protective system, as this involves little extra cost or accommodation compared with the use of common current transformers which would have to be larger because of the combined burden.b. Common voltage transformers are used because duplication would involve a considerable increase in cost, because of the voltage transformers themselves, and also because of the increased accommodation which would have to be provided. Since security of the VT output is vital, it is desirable that the supply to each protection should be separately fused and also continuously supervised by a relay which wil1 give an alarm on failure of the supply and, where appropriate, prevent an unwanted operation of the protection.c. Trip supplies to the two protections should be separately fused. Duplication of tripping batteries and of tripplng coils on circuit breakers is sometimes provided. Trip circuitsshould be continuously supervised.d. It is desirable that the main and back-up protections (or duplicate main protections) should operate on different princlples, so that unusual events that may cause failure of the one will be less likely to affect the other./viewforum.php?f=20继电保护原理发电并将电力供应给用户这就是电力系统的作用。
